Laurence Francis Moroney, Moonee Ponds, near Melbourne, Victoria, Australia Application October 8, 1938, SerialNo. 234,028 In Australia January 24, 1938 10 Claims.

This invention relates to improvements in fittings for vertically slidable window-sashes, shutters or the like (hereinafter, for brevity, termed window sashes), whereby the same can be conveniently moved upwards and downwards and automatically held in selected positions and thereby dispense with sash-balancing weights, pulleys, cords and window frames having boxes for said weights as are now required with conventional window constructions.

A principal object of the invention is to provide a holding device for a vertically sliding window sash, which is of neat, strong and durable construction, capable of being economically manufactured and readily fitted, and in operation will be found to be reliable and efficient by permitting the window sash to be conveniently raised and lowered and rigidly sustained in any required vertical position.

A further object is to provide a holding de- I vice for a vertically sliding window sash, which device has a gripping roller associated with a spring-actuated braking element so constructed and arranged that the roller is wedged against theside of the sash stile and thus firmlyretains it in position, means being provided to regulate the pressure exerted by, the roller whereby .the device is adaptable for window sashes which differ in weight. a

A still further object is to provide a holding device for a window-sash, which will also prevent rattling of the sash in any position to which it has been vertically adjusted, and having means whereby the sash can be restrained against movement in either direction, thereby functioning additionally as a window lock.

According to the invention, I provide a casing adapted to be fitted into a mortise formed in a side member of a window frame. Housed with in this casing is a roller which normally projects outwardly therefrom to press against the side of the sash stile. Bearing against the periphery of the roller is a pivoted element which is acted upon by a spring, the compressional force of which can be' conveniently regulated so that said element while impelling the roller also acts as a brake thereon. The casing has guides for the roller axle so formed that upward. movement imparted to the window sash rotates the roller and causes it to be retracted within the casing against a spring pressure. When the window sash isreleased, the roller is automatically impelled to be wedged against thesash stile, thereby sustaining the window sash in the vertical position to which it has been moved.

The invention is illustrated-by the accompanying drawings, to which reference-is now made for the purpose of a detaileddescription,

Fig. 1 is aside elevation of the holding/device.

Fig.2 is a front elevation of the same.

Fig. 3 is a vertical section on the..1ine:-33 of Fig. 2.

Fig. '7 is a similar view of the-brakingpla-te.

Fig.8 is a perspective view of the casing'which houses the roller.

Fig. 9 is a view of the roller having a fixedaaxle.

Fig. 10 is a fragmentary view of a rollerhaving an axial hole in the ends of which are fitted hardened balls to provide a frictionless axle.

Fig. 11 is an assembly view illustrating thesash holding device mounted'in operative position on a window frame.

Fig. 12 is .a side sectional view showing -'one means for applying the invention to a doublehung window. g

In these views l designates an open-ended casing consisting of a base 2 and two verticalrspa'ced walls 3'and having at its front-end upper and lower vertical flanges 4 and 5, respectively. The said casing with its flanges may be conveniently constructed of metal by die-casting operations.

Housed within the casing l is a' solid roller 6 which normally projects through the front o'f said casing and is adapted to .bear against the side of a stileof a vertically sliding windowxsash indicated by S. This roller may have afixed axle as '1 or, alternatively, it maybe formed with an axial hole 8 at the opposite ends of which are fitted hardened-balls 9 which project laterally from said roller--see Fig, 10and function as a rotatable frictionless axle. The-space between said balls may be filledwith. grease to-lprovide a self lubricating axle for said roller.

Guide grooves [0 are formed-obliquely in the opposed, faces of the vertical walls2 and they extend from points adjacent to the front of said casing to the upper part thereof. These. grooves accommodate'the ends of the roller 'axle 'l, and i'f a roller having hardened balls '9 .as shown in Fi'g. 10 be used, said grooves areof semi-circular configuration in cross section.

A tensioning plate II is pivotally and detachably fitted within the casing I at the rear portion thereof. This plate has at its lower end a hook-shaped lug I2 which is passed through an elongated slot I3 formed in the casing base 2 and engages a recess I4 on the underside of said base. The tensioning plate has at its upper end an ofi-set member I5 wherein a hole I6 is formed to receive the inner end of a horizontal bolt I! which is inserted through a countersunk hole I8 in the upper flange 4. The bolt has a screw head I9 which is accommodated in said countersunk hole, and fitted on its rear end is a nut that is restrained against rotation on the bolt by a lip 2I projecting from said oif-set member and abutting against said nut.

A braking plate 22 is pivotally and detachably secured at its rear end to the tensioning plate I I and it bears evenly upon the periphery of the roller 6. The pivotal connection between the braking plate and the tensioning plate is efiected by forming on the rear end of the braking plate "a hook-shaped extension 23 which is passed throughand is engaged by an elongated slot 24 formed in the tensioning plate above the pivot point of the latter. 7 I

A stout compression spring 25 extends between the upper end'portions of the tensioning, plate H and the braking plate 22, being maintained in operative position by studs 26 and 2'! on the opposed faces of said plates. This spring causes the plate II to exert pressure upon the roller 6, and such pressure canbe conveniently regulated by applying a screw-driver to the screw-head I9 of the bolt IT to rotate the latter and impart piv- I and its vertical flanges 4 and 5, which latter are flush with the window framing as'shown in Fig. 11. 'A fastening screw 28 is passed through a countersunk hole 29 in the lower flange 5 of the casing I into the window framing to prevent displacement of the holding device, which is preferably positioned at or about the midpoint of a double-hung window so that the screw-head IQ of the bolt I1 is conveniently accessible to regulate the spring pressure when the window sash is moved to its lowermost-position.

The roller Ii is preferablyconstructed of metal, and the. tensioning plate It and the braking plate 22 may conveniently be made; of metal by die-casting operations for accurate and economical production.

For. light window-sashes, only one holding device. may be provided, but for general application to windows including those having heavy sash is'being raised or when it is being lowered.

When the window sash is being raised,'the rollerJB which bears against the side of the sash stile is rotated, and the lifting pressure applied to the sash causes said roller to be retracted within, its casing I. The roller is guided up-. wardly and rearwardly within said, casing by the oblique grooves 9' wherein theroller axle is fitted, such movement being against the regution and in such manner as will effectively prevent rattling of the sash.

To'close the window sash sufficient downward force is applied thereto to overcome the lateral pressure exerted by the roller' 6, impelled by spring pressure, upon the sash stile, and in this closing action said roller'is constantly rotating.

When it is desired to lock the Window sash against vertical movement, the bolt I5 is rotated by the use of a screw-driver applied to its head I8 until the force applied by the'spring 25, acting through the braking plate 22, upon the roller 6 is sufficient toprevent rotation of said roller and also its inward and upward movement within the casin I. 'By'this means, the Window-sash can. be conveniently locked in closed position, and it cannot be moved therefrom until the bolt I5 isrotated in the opposite direction to reduce the compressional force of the spring25 and thus release the roller'from the considerable braking pressure exerted thereon by said braking plate. I
